Meg Giry: We don't (in my opinion) see enough of her in either the film or the books. She is drastically different in the film/stage version of POTO than in the book.
In the film, Meg has blonde hair, but in Leroux's book, it's black
In the film, Meg is attractive and Christine's age. In the book, she is rather ugly and a child.
Basically, there are only one or two similarities between ALW's Meg and GL's: she is Madame Giry's daughter and a dancer. Now talk more about this fascinating character here!
